These licensed services, along with unintentional radiators such as digital devices, including computer systems, contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly together in the electronic environment. While this computer system has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference with radio communications services, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:
‡
‡
‡
‡
Reorient the receiving antenna.
Relocate the computer with respect to the receiver.
Move the computer away from the receiver.
Plug the computer into a different outlet so that the computer and the receiver are on different branch circuits.
If necessary, consult a Regulatory EMC representative of Dell Computer Corporation or an experienced radio/television technician for additional suggestions. You may find the FCC Interference Handbook, 1986, to be helpful. It is available from the U.S. Gov- ernment Printing Office, Washington, DC 20402, Stock No.

Dell computer systems are designed, tested, and classified for their intended electro- magnetic environment. These electromagnetic environment classifications generally refer to the following harmonized definitions:
‡
‡
Class A is for business or industrial environments.
Class B is for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards, print- ers, input/output (I/O) devices, monitors, and so on, that are integrated into or connected to the system should match the electromagnetic environment classifica- tion of the computer system.
